CS8321YT3

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The CS8321YT3 is a micropower linear regulator manufactured by onsemi, housed in a TO-220-3 package. It provides a fixed 5V output with a maximum continuous current of 150mA. The device supports an input voltage range up to 45V and features a typical dropout voltage of 0.5V at full load. Key electrical characteristics include a quiescent current of 200µA and a power supply rejection ratio (PSRR) of 75dB at 120Hz. It operates within a temperature range of -40°C to +125°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the component status as discontinued or obsolete through official manufacturer channels before finalizing procurement plans. Ensure compatibility with existing thermal management designs due to the TO-220-3 package constraints.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component for applications requiring a stable 5V rail with minimal ground current draw. The TO-220-3 package facilitates through-hole mounting and heatsinking. Consider the 45V maximum input rating and 150mA output limit to ensure adequate headroom and thermal dissipation under expected operating loads.
